class datumaro.plugins.sampler.algorithm.entropy.SampleEntropy(data, inference)

Bases: datumaro.plugins.sampler.algorithm.algorithm.InferenceResultAnalyzer

Entropy is a class that inherits an Sampler, calculates an uncertainty score based on an entropy, and get samples based on that score.

get_sample(method: str, k: int, n: int = 3) → pandas.core.frame.DataFrame

A function that extracts sample data and returns it. :param method:

• ‘topk’: It extracts the k sample data with the

  highest uncertainty.

• ‘lowk’: It extracts the k sample data with the

  lowest uncertainty.

• ‘randomk’: Extract and return random k sample data.

Parameters

• k – number of sample data

• n – Parameters to be used in the randtopk method, Variable to first extract data of multiple n of k.

Returns

pd.DataFrame

Return type

Extracted sample data
